You might find this useful, it isn't a source of papers, it is first-hand accounts by autistics and what life and other people were like to them. This one, Don't Mourn For Us, is probably the best general description. A quote from it:

You try to relate to your autistic child, and the child doesn't respond. He doesn't see you; you can't reach her; there's no getting through. That's the hardest thing to deal with, isn't it? The only thing is, it isn't true.

Look at it again: You try to relate as parent to child, using your own understanding of normal children, your own feelings about parenthood, your own experiences and intuitions about relationships. And the child doesn't respond in any way you can recognize as being part of that system.

That does not mean the child is incapable of relating at all. It only means you're assuming a shared system, a shared understanding of signals and meanings, that the child in fact does not share. It's as if you tried to have an intimate conversation with someone who has no comprehension of your language. Of course the person won't understand what you're talking about, won't respond in the way you expect, and may well find the whole interaction confusing and unpleasant.

The best single source I know of is Tony Attwood's Complete Guide to Asperger's Syndrome.

As a more general response to your title, you need to learn more about the science, and especially pay attention to how the ideas in the field hang together. A less effective method is to consider how well what you are reading relates to what you already know to be true; unfortunately a lot of real science cannot pass this latter test unless you already know a lot of science.
